More examples CH CH,CH,-COOH Butyric acid（酪酸)：(from Latin butyrum:butter):gives rancid butter its characteristic smell. OH Lactic acid（乳酸)：(from CH CH-COOH Latin lactim:milk):gives sour milk its characteristic taste. CH3(CH2)16-COOH Stearic acid(硬脂酸)：one of the main components of animal fat (saturated fat). OH Citric acid(柠檬酸)gives its characteristic flavor to lemons and HOOC-CH,-C-CH,COOH other citric fruits.Used widely as preservative (antioxidant)and as an COOH additive for tartness
